The Global Positioning System

The Global Positioning System (GPS), the pioneer in navigation technology, was launched by the government of USA for military purposes to guide the missiles and to flow targets. The systems currently consist of 31 satellites (as of March 14, 2018) orbiting twice a daylight in circular motion at an altitude of 20,200 km.GPS provides precision in computing the velocity, position and time. Although, it is subsidized and maintained by Department of Defense, the polite users across the world use it, at free of cost for unlike purposes.TechnologyGPS consists of three subdivisions namely, the satellite or the space segment, user segment and the ascendancy segment.The space segment consists of satellites, the user segment ar the GPS receivers and the control segment helps to oversee the satellite operations. There are five control units to monitor the proper functioning of the satellites, and they are stationed in Krasnosnamensk (Moscow), Schtscholkowo (Moscow), Komsomolsk (Russia), St. Petersburg (Florida) and Ternopil (Ukraine).The reparation of the user is dogged by the line of visibility of four or more satellites and mensural by two factors pseudorange and carrier phase. Usually three satellites points to the coordinates of the user and the fourthly is for the users clock error. The GPS tracking system which is augmented by Low earth Orbit (LEO) which is orbiting at an altitude closest to the earths surface provides comprehensive cyberspace access to remote areas even with low intensive users.Unmanned impractical Vehicles (UAVs) or drones having integrates sensors and GPS receivers uses multicopter technology to fly and capture photos and videos. The drones are capable in identifying objects and avoiding collisions and quickly react to the environmental disturbances like wind, tress, buildings by adjusting their position and movements accordingly. almost importantly, the multicopters have an automatic landing when thither is an interruption of sign als.UsesWhen people touch by Dementia or Alzheimers are lost, the GPS tracking device helps to get back the person. The devices are available in various forms to wear them as come after or as pendant around the neck or in the soles of shoes and or can be even attached to the turn of the patient.Apparently, to avoid restricting such people within nursing homes, it maximised the self-direction and protected them from getting lost. Perhaps, these devices not only help to monitor the location of the person but has fall sensors to alert the caregiver in model of an emergency. The usage of drones in live sports telecasting is an added advantage giving sensational views and movements to the spectators.As they are smaller in size and less noisy, the drones are able to manoeuvre and get some closer shots which helps in conclusiveness making in the corresponding sport.Materials and MethodsResultsConclusionOver the years, there will be a paradigm shift for business running with GPS tech nologies by Global sailing Satellite System (GLONASS) or Galileo.GLONASS was the system developed by the Soviet Union whereas Galileo by the Europe Union (Rizos, 2003). Although, these satellites differ in orbital planes and the altitude from the earth, they provide accurate navigation to the military and the common man. Today, there are several networking and telecommunication companies like St-Ericsson, Qualcomm and Broadcom to offer devices supporting GPS and GLONASS.
